Abstract

La présente invention concerne une soupape destinée à être utilisée en liaison avec des dispositifs microfluidiques comportant un dispositif de sécurité permettant le contrôle de l'écoulement même dans le cas d'une perte de puissance, et donc pouvant être utilisée dans des applications critiques telle que l'administration précise de médicaments dans le temps. La soupape peut être utilisée conjointement avec une pluralité de tubes d'administration de médicaments, et peut être utilisée avec une pompe, telle qu'une pompe électrochimique, pour fournir la force pour la circulation des fluides contenant des médicaments pour l'administration. Dans certaines applications, plus d'un médicament peut être administré et dosé, indépendamment l'un de l'autre au moyen d'une pompe unique avec de multiples réservoirs et soupapes.
